Nursing Process Final Exam Questions

Correct Answer: D

Rationale: The correct answer is D, the Western blot test with ELISA. First, ELISA is used as a screening test for HIV antibodies. If positive, a confirmatory test like Western blot is needed to detect specific antibodies. Western blot is highly specific and confirms the presence of HIV antibodies. E-rosette immunofluorescence is not typically used for HIV diagnosis. Quantification of T-lymphocytes is used to monitor disease progression in HIV but does not confirm HIV infection. ELISA alone is not confirmatory; it needs to be followed by a more specific test like Western blot.

Correct Answer: A

Rationale: The correct answer is A: Adrenal cortex. Primary hyperaldosteronism is a condition where the adrenal cortex produces too much aldosterone hormone, leading to hypertension. The adrenal medulla secretes adrenaline and noradrenaline, not aldosterone, making option B incorrect. The pancreas secretes insulin and glucagon, not aldosterone, making option C incorrect. Option D is incorrect because the adrenal cortex is responsible for aldosterone secretion in primary hyperaldosteronism.

Correct Answer: D

Rationale: The correct answer is D. Carbogen is a gas mixture of carbon dioxide and oxygen. Inhaling carbogen can stimulate respiration due to increased oxygen levels and carbon dioxide acting as a respiratory stimulant. It can also dilate blood vessels, enhancing oxygen delivery to tissues. Additionally, carbogen can help dislodge blood clots by improving blood flow and oxygenation. Therefore, all the choices (A, B, and C) are correct as inhaling carbogen can have multiple beneficial effects on respiration, blood vessels, and blood clot dislodging.

Correct Answer: B

Rationale: The correct answer is B: Reduced sneezing. Decongestants work by constricting blood vessels in the nasal passages, reducing swelling and congestion, which in turn can lead to a decrease in sneezing. Increased salivation (choice A) is not a typical effect of decongestants. Increased tearing (choice C) is more commonly associated with allergies or irritants. Headache (choice D) can be a side effect of decongestants due to their impact on blood vessels, but it does not necessarily indicate effectiveness in treating allergic rhinitis.

Correct Answer: A

Rationale: The correct answer is A because pursed lip breathing helps to slow down and control the exhalation process, allowing the individual to exhale a smaller volume of air with more force. This helps to prevent air trapping in the lungs, improve oxygen exchange, and reduce shortness of breath. B: Incorrect - Pursed lip breathing does not increase expiration but rather controls it. C: Incorrect - While pursed lip breathing can promote deep breathing and better oxygen exchange, its primary purpose is to regulate exhalation volume. D: Incorrect - Pursed lip breathing does not specifically target the upper thorax but rather facilitates a more efficient breathing pattern by reducing air trapping in the lungs.
